Pin Configuration

50Kg Load Cell Documentation
Pin Description:
The 50Kg Load Cell has 4 pins, which are used to connect the sensor to a microcontroller or other devices for signal conditioning and processing. Below is a detailed explanation of each pin:
Pin 1: E+ (Excitation Positive)
Function: Supplies the positive voltage for the load cell's bridge circuit
Voltage: Typically +5V to +10V DC
Connection: Connect to the positive terminal of the power supply or the excitation voltage output of a signal conditioner
Pin 2: E- (Excitation Negative)
Function: Supplies the negative voltage for the load cell's bridge circuit
Voltage: Typically 0V to -10V DC
Connection: Connect to the negative terminal of the power supply or the excitation voltage output of a signal conditioner
Pin 3: S+ (Signal Positive)
Function: Outputs the amplified sensor signal proportional to the weight applied
Signal Type: Differential analog signal
Connection: Connect to the positive input of a differential amplifier or an analog-to-digital converter (ADC)
Pin 4: S- (Signal Negative)
Function: Outputs the amplified sensor signal proportional to the weight applied
Signal Type: Differential analog signal
Connection: Connect to the negative input of a differential amplifier or an analog-to-digital converter (ADC)
Connection Structure:
To connect the 50Kg Load Cell to a microcontroller or signal conditioner, follow these steps:
1. Power Connection:
Connect Pin 1 (E+) to the positive terminal of the power supply (e.g., +5V).
Connect Pin 2 (E-) to the negative terminal of the power supply (e.g., GND).
2. Signal Connection:
Connect Pin 3 (S+) to the positive input of a differential amplifier or ADC.
Connect Pin 4 (S-) to the negative input of a differential amplifier or ADC.
3. Optional:
If using a signal conditioner, connect the excitation voltage outputs to Pin 1 (E+) and Pin 2 (E-).
If using a microcontroller with built-in ADC, connect the ADC input pins to Pin 3 (S+) and Pin 4 (S-).
Important Notes:
Ensure the power supply voltage matches the recommended range for the load cell.
Use a high-precision, low-noise power supply to minimize signal distortion.
The load cell output signal is typically in the range of 1-10mV/V, so a differential amplifier or ADC with high gain and resolution is recommended for accurate weight measurement.
Shielded cables and proper noise reduction techniques should be used to minimize electromagnetic interference (EMI) and noise in the signal path.

Code Examples

### Example 1: Basic Weight Measurement using Arduino

In this example, we'll use an Arduino Uno to read the output voltage from the 50Kg Load Cell and calculate the weight.

Hardware Requirements

Arduino Uno
 50Kg Load Cell
 Breadboard
 Jumper wires

Code
```c
const int loadCellPin = A0;  // Analog input pin for load cell signal
const float loadCellSensitivity = 10.0;  // mV/V
const float fullScaleOutput = 5.0;  // Volts
const float maxWeight = 50.0;  // kg

void setup() {
  Serial.begin(9600);
}

void loop() {
  int sensorValue = analogRead(loadCellPin);
  float outputVoltage = sensorValue  (fullScaleOutput / 1023.0);
  float weight = outputVoltage / (loadCellSensitivity / 1000.0);
  Serial.print("Weight: ");
  Serial.print(weight, 2);
  Serial.println(" kg");
  delay(1000);
}
```
### Example 2: Weight Measurement with HX711 Amplifier using Raspberry Pi (Python)

In this example, we'll use a Raspberry Pi and the HX711 amplifier to read the output from the 50Kg Load Cell.

Hardware Requirements

Raspberry Pi
 50Kg Load Cell
 HX711 amplifier
 Breadboard
 Jumper wires

Code
```python
import RPi.GPIO as GPIO
import time

# HX711 pins
DOUT_PIN = 17
SCK_PIN = 23

# Load cell calibration factor
CALIBRATION_FACTOR = 425.0

GPIO.setmode(GPIO.BCM)
GPIO.setup(DOUT_PIN, GPIO.IN)
GPIO.setup(SCK_PIN, GPIO.OUT)

def read_weight():
  # Read data from HX711
  GPIO.output(SCK_PIN, GPIO.LOW)
  count = 0
  while not GPIO.input(DOUT_PIN):
    count += 1
    GPIO.output(SCK_PIN, GPIO.HIGH)
    GPIO.output(SCK_PIN, GPIO.LOW)
  data = 0
  for _ in range(24):
    GPIO.output(SCK_PIN, GPIO.HIGH)
    data = (data << 1) | GPIO.input(DOUT_PIN)
    GPIO.output(SCK_PIN, GPIO.LOW)
  data = data ^ 0x800000
  weight = data / CALIBRATION_FACTOR
  return weight

while True:
  weight = read_weight()
  print("Weight: {:.2f} kg".format(weight))
  time.sleep(1)
```
Note: The calibration factor (CALIBRATION_FACTOR) may need to be adjusted based on the specific load cell and HX711 amplifier used.

These examples demonstrate the basic usage of the 50Kg Load Cell in different contexts. By modifying the code and adjusting the calibration factor, you can adapt the load cell to various applications, including industrial automation, robotics, and IoT projects.
